ASPHALT PAVEMENT PRESSURE DISTRIBUTIONS USING TEKSCAN MEASUREMENT SYSTEMAnderson, Justin 01 January 2006 (has links)
As a nation that depends so heavily on its infrastructure, the United Statescontinually seeks to better maintain the investment that it has made in its roadways.Asphalt pavements make up the majority of the paved roadways in the United States andultimately contribute to the bulk of the expense of highway maintenance. The goal ofthis research was to develop a means for taking a simple measurement of pressure atvarious interfaces on and within an asphalt pavement structure in an effort to directlyassess the damaging effects of different wheel loadings. It is well known that everincreasing wheel loads and other unusual wheel loading conditions are detrimental to theeffort of maintaining the roadways. The results of the data can be compared to the classicempiricalistic and mechanistic approaches to asphalt pavement design and analysis, aswell as the more modern finite-element computer modeling programs. The Tekscanmeasurement system, which utilizes a very thin matrix based pressure sensitive sensor,has been deemed applicable for measuring pavement pressures. Various types of wheelloadings have been considered throughout this study. It was determined that the type oftire, tire inflation pressure, applied load, and the asphalt itself all have an effect on theresultant pressures on the surface of and within an asphalt pavement structure. Thisresearch may contribute to the understanding of pressure distributions at the tire/asphaltinterface depending on the type of tire, adjustments in tire inflation pressure, and varyingthe wheel load. The results may lead to a better understanding of pressure distributions atvarying depths within an asphalt pavement structure. The ability to quantify thesevariables could assist designers when analyzing and designing asphalt pavements.

Response of blood pressure to relaxation and subliminal suggestionMofield, Jeanne P. January 1985 (has links)
The present investigation compared the effectiveness of an audible relaxation strategy and a subliminal suggestion strategy for lowering blood pressure in a normotensive population. These strategies were compared with each other and with a control group. Data were obtained from 108 females and 37 males on: 1) baseline systolic and diastolic blood pressure; and 2) end of treatment systolic and diastolic blood pressure.It was anticipated that if there was a difference between group means on the dependent measures, the difference would occur between 1) the audible relaxation instruction and the control conditions, and 2) the subliminal suggestion and the control conditions. A one-way multivariate analysis of variance was used to determine pretreatment equivalence of blood pressure in the three treatment groups. A one-way multivariate analysis of variance was used to test for statistical significance on the end of treatment data.The findings revealed that neither treatment strategy was more effective than the other, nor more effective than the control group at the end of treatment. Even though there were slight reductions from pretreatment blood pressure to end of treatment blood pressure in each group, there were no significant differences among groups. The validity and generalizability of these findings were discussed in light of previous research. Recommendations were made for further research.
